You have to complete 7 seals to get to the final room with the rewards. Do not enter the third floor on Isle of Kings or you will have to pay a certain amount of money. Teleporting out means you have to get on the isle using the pearl seal.

Remember: If you decide to stop at any seal, you'll have to go back the way you came, whereas, if you go all the way to the last seal (Banshee Queen), you'll be teleported back to Ghostlands without having to kill anything again.

TIP: Start with the east switch if you go alone then the west switch, remember to use haste from the first switch when it has been pulled because the walls close when anyone steps on the hidden buttons. These buttons are in the path after the magic walls, so if you have a team, it is easier if one person goes to each switch, uses them and 5 people from the team goes trough where the magic walls used to be, and then open again if you have more people on your team. Once the switch pullers come back, make sure no one comes back or they will close the magic walls and you will have to open them again.

After clearing the room, you can open the body on the top of the room to get some junk and a book, the book is brother Fugios diary which has an important role in The White Raven Monastery Quest, but it is optional. You will see a stone surrounded by poison fields. Use your pick on the stone, and a switch will appear beneath it. Use the switch to reveal some stairs. Go down the stairs and go through the teleporter (A). Going through the teleporter on the other side (D) will take you back to the magic walls.

Go south in this long hall and use your pick in the middle of the hall as depicted by the red arrows. If you simply keep going south, you will be teleported back. Go down the pick hole to find the first seal room.

In this room, you will see a blue flame. Every party member must go through the flame, and for every party member that goes through, 2 ghosts and a demon skeleton will be summoned. After going through the flame you will be teleported into a small room with another teleporter. Go through it to go back to the first seal room. First seal is done.

Go south, rope yourself up (B in the previous image) and then continue south. At the end, go west, up the ramp and down into a round chamber (C in 1st seal image). In this room are 3 Ghosts, 3 Stalkers and 4 Demon Skeletons. Go down the stairs.

Walk as far to the south-east from (A in the following image) and you will come to the second seal. You will have to go through: Ghosts, Stalkers, Demon Skeleton and many Scorpions. You need to organize the switches so the match the second image. Then go through the flame and back through teleporter. Only one person needs to do this for the others to go through. Second Seal done.

Backtrack to the stairs at the north-west part this floor (B in previous image). Go down to be faced by ghosts.

You will need to go to the stairs (B in the next image) from where you came down (A in the next image). On the way you will encounter 10 banshees. Keep in mind that you'll never face more than 3 at a time in this area, and usually they are lureable. On the way, you will find a quest door which conceals a box with the Spectral Dress, which is needed for the Explorer Society Quest.

Go north-west to the stairs (from A to B in the next image). Careful as you'll encounter another banshee. Go up and walk on the tiles as shown on the second image. Go through the flame and back through the teleporter. Third Seal done.

Go back down and go to the stairs north from here (C in previous image). Go up into the room where you'll find 5 ghosts, 5 stalkers and 2 demon skeletons. Go down the other stairs, and just follow the way to the next stairs. The next room will be filled with poison fields, Ghosts and Demon Skeletons.

Going up the stairs, you'll be in point A in the next image. Walk north through this room. In the north corner of this room lies the forth seal. This is where you need the vial of blood.

This part gets a little tricky. For every person in your party, you will face 2 warlocks. In the tight corridor to the south, you will see 2 special tiles, like the ones you see in front of the depot box. After stepping on either one, you will spawn the 2 warlocks. It doesn't matter if you step on them again after this. One will spawn north of the tiles, in the corridor, while another will spawn south in the room below, typically the NE corner.

It is ideal for the main blocker to go down first and keep the warlock occupied while the team kills the other. Having killed the other, the blocker should run up again, allowing the team to kill the second warlock. The person going through the tile should simply step on it and go back up the corridor unless they are the blocker.

After the whole team has stepped on a tile, each person must pull the switches in the order as shown below and proceed through the fire. Fifth seal done.

Go from A to B as shown in Image 1, you will go to C shown in Image 2 then go north (you will face 2 Giant Spiders), after that use pick on the place marked in the map and you will go down to Image 3. On Image just go from A to B there is nothing to fight there.
Go up in B in the Image 3, but be carefull there will be a lot of demon skeleton and other creatures to fight up there in Image 4.

In Image 4 go from A to B and use pick to get acess to the sixth seal room.

Once you have found the place to use pick go down and face more demon skeletons, place the pearls where the picture shows and pass through the teleport.

You can use either left teleport or right teleport, it doesn't matter. After you have walked through a teleport, head north through a couple of poison fields and walk through the teleport which you find at the end of the way. In the room where you now arrive, walk through the teleport which you see there. You will be taken back to the spot behind the pearls teleport - just walk in the teleports there to be returned to the spot with the sacrifice tables. Sixth seal done.

The final room is west of the Banshee Queen, you need to get there again all the way from the Ghostlands, it's also possible to go via the Isle of the Kings.

Once you went downstairs you can't go up again. The final room contains 6 Banshees, 2 Dragon Lords and 2 Giant Spiders, usually you have to lure them (depends on the situation). Kill everything, and grab your rewards.

NOTE: Once you left the room (walked through the Magic Forcefield), you can't enter again. So be sure to grab all the rewards.
